    Alignment 300 engine

    Hi again everybody, I'm very confused with the process of alignment engine, the story is that I decided to align my engine and replace the carbon kit because some water was entering through it.
    The problem is that according to the service manual the alignment plate must be fixed in the highest position of the screws, in this way I had to add shims since the motor was very low and now after aligning this is the view you have . It seems to be too high, it makes me suspect the procedure in the manual to lift the alignment plate, because if I don't do it and leave it in the normal position where it falls under its own weight, the motor was previously aligned correctly. Based on your experience with the alignment tool, you set the plate in the highest possible position since it has a little play through the holes in the tool... I'm going to go crazy hehehe

    This piece is inserted into the thur-hull insert.....be sure to grease it up some before placing into the thur-hull insert. Same for the alignment shaft. The manual should also have instructions for marking the alignment shaft in two places for the fore/aft measurements.

    My guess for the push up - would be more room to shim the motor - if needed - if it were at the bottom - you may not have the room to subtract shims - as long as you square up the motor - I don't think you need to push the plate up if you have shimming room - Good luck.

    I think that part only works on the older ski not the 300, I had to make a custom one for the 300 , if I remember correctly.

    The thur-hull insert is smaller or larger than previously?

    I just used a pump from a 2008 RXP on the 2020 RXTX 300 - bolted right up - I would assume the same pump alignment tool I used on the 2008 would work on my 2020?

    put the 15/25 159mm on my 2020 - slightly faster - better than OEM and 13/18 solas In my humble(worthless) opinion.

    Ride on and enjoy

    In this video I show the two possible ways of placing the plate, I definitely do not know which is the correct way to do it since if I fix it up or down by its own weight the alignment form will change ...

    I'd recommend shimming between the top of the mount and the engine if it only needs a little shimming. Or be prepared to break off a motor mount bolt...like I on my 19px with like 19 hrs on it. Then you get to pull the motor out. I even heated mine with a torch before trying...still broke one off.
